| Impact Description | Research comparing native Daphnia spp. to the exotic Daphnia lumholtzi has found that competition was lower than expected. Daphnia lumholtzi is a tropical species and is adapted to warmer temperatures than native North American Daphnia. Thus, D. lumholtzi population sizes increases in late summer when native Daphnia populations are lower. As a result, D. lumholtzi may be filling a vacant "temporal niche" in the warmer months. |
